Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SMT&R' confirms the tape-and-reel packaging format required for automated assembly processes. Ensure the component meets RoHS compliance standards as indicated for Isocom surface-mount variants. Cross-reference the manufacturer part number with official Isocom documentation to confirm pinout compatibility and lead spread specifications before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-density mounting and robust electrical isolation are required in industrial or computing environments. The 70V minimum collector-emitter breakdown voltage makes it suitable for switching applications requiring moderate voltage handling. Consider the surface-mount form factor for PCBs where space constraints preclude through-hole DIP packages.
